AUTOMOBILE RADIATOR:

T o aZZ whom it may concern Be it known that I, JAooB B. BEAM, a citizen of the United States residing at Punxsutawney in the county of Jefferson and State of l?ennsylvania have invented new and useful Improvements in Automobile Radiators, of which thefollowing is a specification. V

This invention relates to radiators'ofor use in connection with the cooling system of internal combustion engines.

" The-primary object of the invention is to provide, a radiator having I a casin stamped from sheet'm'etal in which the said casing is utilized for the circulation of water containing upper and lower water chambers and independent tube sections communicating therewith to provide a water circulation, the casing being also provided with a front finishing beachobviating the necessity of adding an additional finishing casing and 7 thereby simplifying fand" irnproving the construction of the radiator and reducing the cost of manufacture} 7 Another object of the invention is to provide simple and novel, means of securing the parts together, so as topermit of theready removal andinsert-ion of the independent tube sections.-, i v- A still further object, is .to provide means for temporarily closing'the-openings through whichcommunication is established between the tubesections and'the water chambers, so as to permit of theremoval ofone or more of the tube sections without interfering with theuse of the radiator. r 1

' Other objects and advantages of the invention Willappear as the following description is read in connection with the accompanying drawings. v ln thefdrawingsz Y 1 r v Figure 1 is a sectional elevation oi-eradiator embodying the present invention; f Figure 2 is a section on'the line.22'o'f Figurely Figure 3 is an enlarged sectional view illustrating the manner of temporarily clos ing theopen'ings in-thewaterchanibers; z Figure 4; is. an enlarged detail sectional view'illustrating the manner of temporarily closing the openings in the water chambers in a different form of the invention,- the upper water. chamber being shown in this figure; and y V Figure 5' illustrates the manner of apply- Specification of Letters Patent. 1 p atg fedolfla 14, 1922, Application filed August 17,1918.

ing this closingmeans from the rear ofthe radiator. t '1 In'the usual construction otradiatorsythe radiator proper is ordinarily made of a single casting, which contains the upper and lower water chambers connected together by the water circulating tubes In this form of. radiator it ,isnecessa'ry to make the casting of considerable thickness cure proper strength and to prevent damage to thefcastingwhen the core is removed. In order to present aqneat and-attractive apg pearan'ce, it is necessary to use'in connection in order to sewitljithis ca g, a cover orc'asing, therebv 1 I addingto'the cost of'manufac'ture and. the amount of material necessary 'toconstruct a radiator. 1

In. order-to overcome these and other disadvantagesthepresentinvent on contemplates 'th'e. provision. of a casingstamped from sheetmetal, int which there is formed upperfand low'er water'charnbers connected". 7 together by independent tube sections T or units, thejnovel manner 'o'f forming thecasingj simplifying its construction and 'niaterially reducing the cost of its manufacture In, the accompanying drawings, the radiator shown-comprises a casing which in cludes an upper water chamber110=and a lOWGlJVfi-tGI' chamber 11. Theiupper water chamber is formed by stamping-the frontwall112; the, t0p-Wal1-13' and the "si'de-wall14 froniisinglejpieceof sheet-'inetal, the latter forming means for connectionwith the lower water chamber a'swill behereinafter dc scribed. The to'p walll3 'is provided 'with a suitable, opening 15, which is surrounded by a nipple 16 for convenience in filling the radiator. v The bottom'wall 17 and the rear wall 18 of jthelnpper chamber '10 isfalso formed of a? single piece of sheet metal stampedginto the proper shape and having its edges. secured to the. 'rear and bottom edges ofthe top and'fr'ont walls respectively, bybrazing or other suitable means The bottom wall 17 is'providedzwith a tubular extension 19 for connection'in the ordinary g anner with the water.circulating-system ofan engine. -;The lower water chamber hasits top wall 20, its bottom wall 21 andiits rear wall 22 starnped from a-single pieceof sheet metal, while the front wall 23 isfseparatelygformed and brazed or otherwise and bottom walls.

.secured'to the top V 1 10 of; a key4-7.

The water circulating tubes 24 are arranged in independent tube sections and include upper water headers 25 and lower water headers 26, which are adapted to communicate through openings 27 and 28 formed respectively in the opposed walls of: the upper and lower water chambers, these openings being provided with suitable gaskets 29 to-prevent leakage;

In assembling the. radiator, the independent tube sections are connected with the top water chamber and the bottom water chamber is then adjusted upon the opposite ends of these sections, this chamber being held in position through the medium of screws or bolts 30,prov1dedat each end of the bottom water chamber, these screws passing-throu h am'etal block 31, brazed to each of the. si e walls of the casing, this last mentioned-1 block being provided with an offset 32' to provide: edging flanges by means of which the radiator maybe secured upon the frame of the vehicle. 1

As. will be seen. from: the foregoing de. scription and the] accompanying drawings, each of the independent tube sections isremovable and the V radiator may be used after the removal of one or more of these sections, the openings provided in the water chambers being temporarily closed by suitable means,

one of which is illustrated in Figure 3'.

This consists of a 'compre'ssibleblock 33, which is positioned upon the sha 'nk of a T-bolt 34. Also positioned upon the shank of this bolt-is a disk 35and a clamping nut 36. By reference to Figure 3-it will beseen that the bolt 34 may have its head inserted through any one of the openings in the water chambers and the compressible block 33 positioned against the flange, the said block being securely held in such position by adjusting the nut 36.- p

In Figure 4. there is illustrated amodified form of this feature of the invention, the

same beingjshown applied to the radiator of different construction, such as is illustrated in one of my pending applications. In this form of the invention there isprov ided a sle ve 3-7, one end off which is suitably secured. within an opening-38 in the front wall of the water chamber. This sleeve is provided with a compressiblelini-ngBQ having an opening extending therethrough for the passage of the. shank of a bolt 40, the said shankbeing of slightly greater diameter than the opening 41in the compressible 1m, ing 39. Secured upon the head '42 of the bolt 40 is a compressible member 43', which is adapted for insertionfwithin the opening 44 through which communication is estab l ished. between the water chamber and, the water circulating tubes, The belt 40 is 'pro vided with a" reduced threaded extension '45 for eng gement; with the threaded socket 46 When it, desired to close the opening 44 after the removal of a tube section, the bolt 40 is moved inwardly to engage the compressible' mber 4 With the opening 44 in s the manner shown in Figure 4. The compressible nut of the lining 39 serves to securely hold the member in this position. hen it is desired to remove the-member 43 from the opening 44 for the purpose of reestabli'shin'g communication between the water chamber and the independent tube secthat theclosingdevi'ce is inserted fromthe rear of the radiator, the sleeve 49 being secured around an opening 50 provided in the rear wall of the water header 51; of eachof the independent tube sections. This sleeve 49 carries a compressible member 52, within which operates a bolt 53 carrying. a compressible head 54, which is adaptedto engage the opening; 55 through which. communication is establishedbetween the water chamber and the header 51 The bolt 53 is withdrawn to open communication by, en-

gaging the key .47'with threaded end 56 of thebolt'53.- c It is believed that from the foregoing description taken in connection with the ac? companyin'g drawings, the construction and advantageswill be apparent.- The right is} reserved .to make such changes in the form v and proportion thereof as will fall within the scope of the appendedclaimsi Havingl'described the invention, i
